Very dark, organic delay. Inspiring with just the right amount of options that are immediately available from the front panel. Great sound quality though the modulation (in combination with the compression & tone) is what sets it apart from most other really simple guitar pedal delays (good 'bad' sound quality of the days of yore is easily achievable). Not cheap but worth it. the modulation has just three settings (none-medium-heavy) but they are well implemented. Nice natural blend of effected and non-effected sound.
I use it mostly on synth sounds to make them instantly old and worn. Also like the no non-sense design of the thing. For what i do stereo would have been nice, but there are workarounds for that in my multi-effect units (or software) anyway.
Delay times are not long, 500ms, pairing with another delay could even make sense.
The infinite feedback from this box will not blow your speakers btw so you can tweak all you want for hours on end without any worries there.
I bought this for the sound character, not the versatility and am not disappointed
4.5 stars.
